GAB-TRUCIi mosses.

To all whom it may concern:

Be it known that I, PINK VVILLIAMs, a

citizen of the United States, residing at Anniston, in the county of Calhoun and State of Alabama, have invented certain new and useful Improvements in Car -Trucks, of which the following is a specification.

This invention relates to car trucks, and more particularly to one having the columns formed from pressed steel.

The object of the invention is to form columns of this character which are simple in construction, durable, and efficientin operation, and may be quickly and rigidly assembled to the other parts of the usual car trucks.

Other objects and advantages will be apparent from the following description, and it will be understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the accompanying drawings: Figure 1 is a side elevation of a car truck equipped with my improved columns. Fig. 2 is a sectional view taken on line 22 of Fig. 1. Fig. 3 is a similar view on line 33 of Fig. 1. Fig. 4 is a similar view on line 4-4 of Fig. 1. Fig. 5 is a perspective view of one of the columns removed from the truck. Fig. 6 is a perspective view of one of the column guides removed from the bolster. Fig. 7 is a similar view of a modified form of a column guide. Fig. 8 is a similar view of another form of column guide.

Referring to the drawings, the numeral 1 designates the upper arch member, and 2 the lower arch member, both of the usual construction, and between which the columns 3 are positioned. Each of the columns 3 are formed from pressed steel, and comprise a body portion 4, and a base 5 having oppositely disposed ears 6. The body portion is so formed that flanges 7 are provided, thereby forming a channel 8 for the bolster guides 8. It will be noted that the bolster guides are rigidly secured to the truck bolster, and not to the columns as usual. The column is provided with outwardly extending lips 9 and 10 and inwardly extending lips 1111. The lips 10 and 11 are formed with the base 5, and are adapted to rest upon the lower arch mem- Specification of Letters latent.

I ber 2, and the lip 9 is adapted to rest upon the under face of the upper arch member 1.

Formed integral with one of the flanges 7 is an extension 12 having its outer end 13 bent at right-angles, and its outer edge formed with a flange 14 to strengthen the same. Ttiveted or otherwise suitably secured to the extension 12 is a plate 15, hav ing its end 16 bent parallel with the end 13 of the extension 12. Suitable bolt openings are formed in the portions 13 and 16, and are arranged in registered relation, so that the bolts 17 may be passed therethrough and held therein by a cotter pin or any suitable fastening means. Pivotally connected to the bolts 17 are brake hangers 18, preferably formed from rolled metal and being so formed that a loop 19 is provided, and parallel hanging arms 2020 have their ends sustained by the bolt 17.

A spring plank 21 has its ends bolted or otherwise suitably secured to the bases 5 of each column. Supported upon the spring plank 21 are the usual bolster springs 22 adapted to sustain the truck bolster 23, having the bolster guides 8 secured thereto for vertical movement within the channels 8' of the columns 3.

The columns are secured to the lower arch bars by bolts passing through the openings formed in the lips 1111 and by a bolt 24, said bolt passing through suitable openings formed in the outwardly extending lips 9 and 10. To add rigidity to the columns, tubes 25 are arranged between the lips 9 and 10, and parallel with the body portions of the columns, and through which the bolt 24 passes. The bolt 24 is screw-threaded at its lower end, and passes through the lower arch member 2 to receive a nut for securely fastening the columns in their proper posi tions.

The bolster guides 8 are formed from pressed steel, and comprise attaching flanges 26 and a substantially tJ-shaped channel ongaging portion 27 having flanges 2828. A channel engaging portion 27 is preferably secured to the bolster guide proper by clamping flanges 2929, from this construct-ion it will be seen that the flanges 2828 engaged in the channel 8, and by so doing, undue friction is prevented during the vertical movement of the truck bolster, to which said guides are suitably secured.

' In the modified form of the bolster guides, shown in Fig. 8 of the drawings, the same is formed with an attaching plate and inwardly extending channel engaging flanges 3131.

In the modified form of the bolster guides, as shown in Fig. 7 of the drawings, the guide consists of a substantially U-shapcd member 32, and provided with attaching extensions 33-33.

What is claimed is:

1. In combination with a bolster,- having pressed steel column guides secured thereto, the upper and lower arch bars, pressed steel columns comprising body portions, bases,

'side flanges forming a channel for the guides,

an extension formed integral with one of the flanges and having its end bent at right angles to said extension, a plate secured to the extension, and having its end bent parallel with the bent end of the extension, a bolt passing through the parallel bent ends, a brake hanger pivotally supported by said bolt, lips formed with the base and extending inwardly, a single lip formed at the top of the body portion and a lip formed at the lower edge of the base, both of said lips extending outwardly, suitable bolt openings formed in the lips, means for securing the inwardly extending lips to the lower arch member, a tube arranged between the lip at the top of the body portion and the lip formed in the base, and a bolt adapted to pass through said tube to strengthen the column and secure the last mentioned lips to the arch bars, a spring plank having its ends secured to the base of each column, coil springs supported thereon and adapted to sustain the bolster.

2'. The combination with a bolster, of upper and lower arch bars, pressed steel columns arranged between the arch bars, said columns being provided with side flanges to form channels, column guides carried by the bolster and adapted for vertical movement in said channels, and means for securing the columns to the arch bars, spring planks having their ends secured to the columns, springs mounted on said planks and adapted to sustain the truck bolster.

3. The combination with a truck bolster, of upper and lower arch-bars, pressed steel columns secured between the arch-bars, channels formed in said columns, guides secured to the truck bolster for vertical travel in the channels, said guides having bolster attaching flanges and U-shaped channel engaging portions.

In testimony whereof I aflix my signature, in the presence of two witnesses.
